Virtualized Evolved Packet Core (vEPC) is a major breakthrough in network function virtualization (NFV). When
asked where they have deployed NFV in production networks, communication service providers (CSPs) consistently name vEPC as one of the top answers. Why is that?
In order to maximize their processing capacity, CSPs virtualize a subset of their network applications, including
mobile edge computing (MEC), base stations (small/macro
cells) and the mobile core, because these systems use a
large bandwidth.
The mobile packet core builds the foundation of the core
network on which mobile CSPs offer IP-based services to
their customers. Implementing vEPC solutions can help
CSPs obtain the scale necessary to accommodate growing
numbers of subscribers and large amounts of traffic or
connections while controlling costs and improving on quality of experience (QoE). In the past, evolved packet core
(EPC) solutions were deployed on purpose-built hardware.
NFV enables operators to deploy EPC c

To keep up with sweeping global economic and societal changes, public services organizations are undergoing significant technology-driven transformation. Aging populations, rapid urbanization, political instability, concerns about sustainability and resiliency, and changing worker and resident expectations are driving public services organizations to radically improve operations and service delivery. At the core of this transformation is the ability to collect and process vast amounts of data to help to improve outcomes and services. One way to generate this data is through the Internet of Things (IoT) — which IDC defines as a network of networks of uniquely identifiable endpoints or “things” that communicate without human interaction using IP connectivity. The IoT is a transformational technology that can reshape the public sector, enabling improved outcomes and new services such as remote patient monitoring, advanced traffic solutions and predictive policing.

In August 2008, Computerworld invited IT and business leaders to participate in a core network services survey, that included specific questions about their DNS infrastructures and the costs of IP address management. The survey was fielded via targeted broadcasts to Computerworld customers, as well as through an invitation on Computerworld.com. The survey was commissioned by Infoblox, but the data was gathered and tabulated independently by Computerworld Research. The following report represents top-line results of that survey.

Today’s networks support more applications, traffic, users, and devices than ever before – a trend that only increases on a daily basis. At the heart of all IP networks live core network services, like DNS, DHCP, and RADIUS that are crucial for keeping traffic flowing, users connected, and applications available.

In the next few years we shall see explosive growth in the use of video conferencing as a fundamental tool for businesses to enhance communication and collaboration between employees, partners and customers. The technology has developed considerably from early adopters to its current form of mass market roll-out. It’s anticipated that nearly half of information workers will have some type of personal video solution in 2016, up from just 15% today. With video conferencing becoming a core component of IT infrastructure that enables communication and collaboration, businesses will be looking to providers of telephony, business applications and network infrastructure services to include this capability as part of their offering. This report will examine the basic components of the technology, considerations for deploying video conferencing solutions, and will introduce the Polycom® RealPresence® Platform to readers

Core network services, which include name resolution (DNS), IP address assignment (DHCP) and management (IPAM), are used by just about every networked application, which these days includes pretty much every non-trivial application.

The bank wanted to modernize its global data center core and edge networks to move to the next stage of its private cloud journey. The bank has long recognized the advantages of server virtualization, and it wanted to move more aggressively to a software-defined data center. The bank was virtualizing all services, including compute, storage, and network, to gain greater business flexibility and deliver cost savings. But first, it needed an elastic, flexible, and production ready network to connect its data centers.
The bank wanted a dynamically scalable network to interconnect its data centers in Europe, Asia, and North America, so that it could move toward a fully automated, self provisioned cloud. The global network needed to deliver performance at scale for the company’s highly virtualized resources, while also supporting integration of legacy assets into its software-defined data centers.
